Hi all! I'm confused by planner choice: seqscan but not index scan when index scan cost is much cheaper. 1st plan: https://explain.depesz.com/s/Cti#l8 2nd plan (with "set enable_seqscan = off"): https://explain.depesz.com/s/qn0I#l8 Look at 8th row: this nested loop decided to join the second node by using seqscan (1st plan) when index is available (2nd plan). Index scan is much cheaper (0.430 over 257.760). What am I missing? And thanks for any reply!
